LOOSE-LEAF LEDGER.

Original application filed August 15, 1917, Serial No. 186,342. Divided and 1918. Serial No. 210,239.

To all whom it'may concern:

Be it known that I, JOHN SOHADE,21. citizen of the United States, residing at Holyoke, county of Hampden, State of Massachusetts, have invented certain new and useful Improvements in Loose-Leaf Ledgers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in a loose leaf binder and particularly to a loose leaf ledger of that type known as sectional ledgers which are used by book-keepers in department stores and other business establishments.

The invention particularly resides in a sheet-transferring device that is interposed between the post parts of the ledger sections, when the latter are separated, for establishing a continuous guide from one post part to the companion post part.

In the drawing Figure 1 is an end view of a loose leaf ledger in its opened position as it ordinarily appears before the ledger sections are separated.

Fig. 2 is an elevation of one form of the sheet transferring device operatively disposed on the loose leaf ledger which latter is supported on a particular form of book holder.

Fig. 3 is a similar view illustrating a further embodiment of the sheet transferring device in which separable sections are disposed on a flat table.

Fig. 4 is a still further modification of the sheet transferring device, and

Fig. 5 is a detail top plan of a Suitable latch to retain the ledger sections together.

Similar numerals of reference denote like parts in the several figures of the drawing.

This application is a division of my pending application, Serial N 0. 186,342, filed August 15, 1917.

Referrin in greater particularity to the drawings, tlie numerals 1 designate the pair of cooperating and separable back sections of the loose leaf ledger, each of which comprises an L-shaped bar having its corner or angle strengthened by the rectangular braces Specification of Letters Patent.

Patented Nov. 5, 1918.

2 and having the free edge of its base flange turned inwardly, as at 3, and backwardly over the base to form a return portion 4 of concavo-convex cross section. The base and concavo-convex part are formed at intervals this application filed January 4, v

with registering apertures (not shown) and the male and female parts of thebinder posts 6 have flared heads and are inserted nwardly through the apertures of the base and concave-convex portion 4, said flared heads seating in the base apertures and being securely retained in operative position by the cheek plates 7. As'before stated, this invention, while it relates to loose leaf binders in general, has particular referenceto loose leaf ledgers of the style and type known as sectional ledgers,

the sections after separation being abutted together flatly on a desk or table so that a bookkeeper may work on the sheets as in an ordinary ledger. To eliminate the tedious and impractical method of lifting up the leaves from one part or section and manuall depositing them on the posts of the other section, in turning the leaves, a sheet-trans.- ferring device is provided'for guiding the sheets from the posts of one binder section to the posts of the other section so that the bookkeeper merely has to turn the leaves in the ordinary manner.

This sheet transferring. device comprises a pair of companion guide elements 8 and 9, one element 8 having a reduced shank 10 for insertion in a female post part, the shoulder 11 supporting the element on top of the post, and the other element 9 having a socket 12 to receive and seat on the male post part. The upper end of one guide element is hollowed or socketed and the opposing end of the other element is rounded to form a ball and socket joint 13 between the guide elements so that thesheets or leaves when turned may readily pass from one post part to the other on one continuous track or guide without interruption or inconvenience through an irregular joint.

While the ball and Socket joint affords a smooth and finished joint permitting 'universal movements and varying dispositions of the covers and back sections, it will also be noticed that the guide elements are freely separable so that one binder section may readily be carried about the office by itself or have another section substituted where it is desired to transfer certain pages from one ledger to another.

When the transfer arches 8, 9, are straight, as shown in Fig. 2, it is desirable to support the binder sections at an inoline by a book holder or rest id in order that the bailed end of one guide .element may properly fit the socket of the other element. But these sheet transferring devices may have their complementary separate sections, forming arches, of any desired shape, such as angular, as shown at 20 and 21 in Fig. 4, or curved as shown at 18 and 19 in Fig. 3, and therefore I do not wish to be limited in this respect.

Should it be desired to lock the binder sections together in their abutting relation, this may be accomplished by striking out a pair of hinge knuckles 15 from the base of one L'sha-ped bar and pivoting the latch 16 therebetween for swinging over and engaging in a keeper cut-out 17 of the companion bar. In the position shown in Fig. 2 the book rest will conveniently serve as a means for preventing the complementary arch sections Copies of this patent may be obtained for five cents each, by addressing the or guide elements from separating and becoming inoperative.

I claim 1. In a loose leaf binder, a transfer device composed of two separable binder sec tions having telescopic post parts, and sheet transferring devices comprising two independent separate sets of guide elements which are carried respectively by the post parts of said sections when the latter are separated, the free ends of said guide elements being abutted in separable contact.

2. In a loose leaf binder, separable binder sections having telescopic post parts, and sheet transferring devices carried by the post parts when the sections are separated, each device being composed of two independent separate guides which abut, the abutting end of one element being formed into a socket and the abutting end of the other element being round whereby a ball and socket contact is formed.

In testimony whereof I affix my signature.

JOHN SCHADE.
